Assembly
1. Install the front roller bearing 19 of the secondary shaft onto the secondary shaft.
2. Orient gear 18 of the 4th gear with the wide flange towards the drive gear of the main gear and press it onto the shaft until it stops, having first heated it to a temperature of 120°C by any available method, but without using an open flame.
3. Select the thickness of the retaining ring 17 from those supplied as spare parts so as to select the maximum axial clearance between it and the 4th gear pinion. Install the retaining ring on the shaft. Retaining rings with a thickness of 2.35 are supplied as spare parts; 2,38; 2,41; 2.44 and 2.47 mm.
4. Orient gear 16 of the 3rd gear with the wide flange towards the gear of the 4th gear and press it onto the shaft until it stops, having first heated it to a temperature of 120°C by any available method, but without using an open flame.
5. Select the thickness of the retaining ring from those supplied as spare parts so as to select the maximum axial clearance between it and the 3rd gear pinion. Install the retaining ring on the shaft. Retaining rings with a thickness of 1.50 and 1.60 mm are supplied as spare parts.
6. Install needle bearing 14 and 2nd gear gear 13.
7. Install synchronizer 11 of 1st and 2nd gears on the shaft, complete with blocking rings, in accordance with the previously made marks.
8. Install needle bearing 7 and 1st gear gear 9.
